A downburst affecting an area greater than 4 kilometres across and having damaging winds. Macrobursts are generally longer-lived than the smaller microbursts. Macrobursts have been documented to 'wrap-up' into weak tornadoes, however these would be classified as gustnadoes as they are not directly associated with storm-scale rotation. See also microburst.

A strong down draft (down burst) greater than 4 km wide that can occur beneath a thunderstorm. A down burst less than 4 km is called a "microburst". Thunderstorm winds that exceed 58 miles per hour are a feature of a "Severe Thunderstorm".
